TECHNICAL FIELD

The disclosed embodiments relate generally to devices with touch-screen displays, and more particularly to scrolling lists and to translating, rotating, and scaling electronic documents on devices with touch-screen displays.

BACKGROUND

As portable electronic devices become more compact, and the number of functions performed by a given device increases, it has become a significant challenge to design a user interface that allows users to easily interact with a multifunction device. This challenge is particularly significant for handheld portable devices, which have much smaller screens than desktop or laptop computers. This situation is unfortunate because the user interface is the gateway through which users receive not only content but also responses to user actions or behaviors, including user attempts to access a device's features, tools, and functions. Some portable communication devices (e.g., mobile telephones, sometimes called mobile phones, cell phones, cellular telephones, and the like) have resorted to adding more pushbuttons, increasing the density of push buttons, overloading the functions of pushbuttons, or using complex menu systems to allow a user to access, store and manipulate data. These conventional user interfaces often result in complicated key sequences and menu hierarchies that must be memorized by the user.

Many conventional user interfaces, such as those that include physical pushbuttons, are also inflexible. This is unfortunate because it may prevent a user interface from being configured and/or adapted by either an application running on the portable device or by users. When coupled with the time consuming requirement to memorize multiple key sequences and menu hierarchies, and the difficulty in activating a desired pushbutton, such inflexibility is frustrating to most users.

As a result of the small size of display screens on portable electronic devices and the potentially large size of electronic files, frequently only a portion of a list or of an electronic document of interest to a user can be displayed on the screen at a given time. Users thus will frequently need to scroll displayed lists or to translate displayed electronic documents. Users also will need to rotate and to scale (i.e., magnify or de-magnify) displayed electronic documents. However, the limitations of conventional user interfaces can cause these actions to be awkward to perform.

Furthermore, scrolling displayed lists and translating electronic documents can be awkward on both portable and non-portable electronic devices with touch-screen displays. A user may become frustrated if the scrolling or translation does not reflect the user's intent. Similarly, a user may become frustrated if rotation and scaling of electronic documents does not reflect the user's intent.

Accordingly, there is a need for devices with touch-screen displays with more transparent and intuitive user interfaces for scrolling lists of items and for translating, rotating, and scaling electronic documents that are easy to use, configure, and/or adapt.

SUMMARY

The above deficiencies and other problems associated with user interfaces for portable devices and devices with touch-sensitive displays are reduced or eliminated by the disclosed device. In some embodiments, the device has a touch-sensitive display (also known as a “touch screen”) with a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through finger contacts and gestures on the touch-sensitive display. In some embodiments, the functions may include telephoning, video conferencing, e-mailing, instant messaging, blogging, digital photographing, digital videoing, web browsing, digital music playing, and/or digital video playing. Instructions for performing these functions may be included in a computer program product configured for execution by one or more processors.

DESCRIPTION OF EMBODIMENTS

Reference will now be made in detail to embodiments, examples of which arc illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

Embodiments of a portable multifunction device, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device such as a mobile telephone that also contains other functions, such as PDA and/or music player functions.

The user interface may include a physical click wheel in addition to a touch screen or a virtual click wheel displayed on the touch screen. A click wheel is a user-interface device that may provide navigation commands based on an angular displacement of the wheel or a point of contact with the wheel by a user of the device. A click wheel may also be used to provide a user command corresponding to selection of one or more items, for example, when the user of the device presses down on at least a portion of the wheel or the center of the wheel. Alternatively, breaking contact with a click wheel image on a touch screen surface may indicate a user command corresponding to selection. For simplicity, in the discussion that follows, a portable multifunction device that includes a touch screen is used as an exemplary embodiment. It should be understood, however, that some of the user interfaces and associated processes may be applied to other devices, such as personal computers and laptop computers, that may include one or more other physical user-interface devices, such as a physical click wheel, a physical keyboard, a mouse and/or a joystick.

The device supports a variety of applications, such as a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a blogging application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that may be executed on the device may use at least one common physical user-interface device, such as the touch screen. One or more functions of the touch screen as well as corresponding information displayed on the device may be adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch screen) of the device may support the variety of applications with user interfaces that are intuitive and transparent.

The user interfaces may include one or more soft keyboard embodiments. The soft keyboard embodiments may include standard (QWERTY) and/or non-standard configurations of symbols on the displayed icons of the keyboard, such as those described in U.S. patent application Ser. No. 11/459,606, “Keyboards For Portable Electronic Devices,” filed Jul. 24, 2006, and U.S. patent application Ser. No. 11/459,615, “Touch Screen Keyboards For Portable Electronic Devices,” filed Jul. 24, 2006, the contents of which arc hereby incorporated by reference herein in their entirety. The keyboard embodiments may include a reduced number of icons (or soft keys) relative to the number of keys in existing physical keyboards, such as that for a typewriter. This may make it easier for users to select one or more icons in the keyboard, and thus, one or more corresponding symbols. The keyboard embodiments may be adaptive. For example, displayed icons may be modified in accordance with user actions, such as selecting one or more icons and/or one or more corresponding symbols. One or more applications on the portable device may utilize common and/or different keyboard embodiments. Thus, the keyboard embodiment used may be tailored to at least some of the applications. In some embodiments, one or more keyboard embodiments may be tailored to a respective user. For example, based on a word usage history (lexicography, slang, individual usage) of the respective user. Some of the keyboard embodiments may be adjusted to reduce a probability of a user error when selecting one or more icons, and thus one or more symbols, when using the soft keyboard embodiments.

Theaudio circuitry110, thespeaker111, and themicrophone113 provide an audio interface between a user and thedevice100. Theaudio circuitry110 receives audio data from theperipherals interface118, converts the audio data to an electrical signal, and transmits the electrical signal to thespeaker111. Thespeaker111 converts the electrical signal to human-audible sound waves. Theaudio circuitry110 also receives electrical signals converted by themicrophone113 from sound waves. Theaudio circuitry110 converts the electrical signal to audio data and transmits the audio data to the peripherals interface118 for processing. Audio data may be retrieved from and/or transmitted tomemory102 and/or theRF circuitry108 by theperipherals interface118. In some embodiments, theaudio circuitry110 also includes a headset jack (not shown). The headset jack provides an interface between theaudio circuitry110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

The I/O subsystem106 couples input/output peripherals on thedevice100, such as thedisplay system112 and other input/control devices116, to theperipherals interface118. The I/O subsystem106 may include adisplay controller156 and one ormore input controllers160 for other input or control devices. The one ormore input controllers160 receive/send electrical signals from/to other input orcontrol devices116. The other input/control devices116 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s)160 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g.,208,FIG. 2) may include an up/down button for volume control of thespeaker111 and/or themicrophone113. The one or more buttons may include a push button (e.g.,206,FIG. 2). A quick press of the push button may disengage a lock of thetouch screen112 or begin a process that uses gestures on the touch screen to unlock the device, as described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, which is hereby incorporated by reference herein in its entirety. A longer press of the push button (e.g.,206) may turn power to thedevice100 on or off. The user may be able to customize a functionality of one or more of the buttons. Thetouch screen112 is used to implement virtual or soft buttons and one or more soft keyboards.

The touch-sensitive display system112 provides an input interface and an output interface between the device and a user. Thedisplay controller156 receives and/or sends electrical signals from/to thedisplay system112. Thedisplay system112 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects, further details of which are described below.

A touch screen indisplay system112 is a touch-sensitive surface that accepts input from the user based on haptic and/or tactile contact. Thedisplay system112 and the display controller156 (along with any associated modules and/or sets of instructions in memory102) detect contact (and any movement or breaking of the contact) on thedisplay system112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that arc displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen in thedisplay system112 and the user corresponds to a finger of the user.

The touch screen in thedisplay system112 may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen in thedisplay system112 and thedisplay controller156 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with a touch screen in thedisplay system112. A touch-sensitive display in some embodiments of thedisplay system112 may be analogous to the multi-touch sensitive tablets described in the following U.S. Pat. No. 6,323,846 (Westerman et al.), U.S. Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932 (Westerman), and/or U.S. Patent Publication 2002/0015024A1, each of which is hereby incorporated by reference herein in their entirety. However, a touch screen in thedisplay system112 displays visual output from theportable device100, whereas touch sensitive tablets do not provide visual output. The touch screen in thedisplay system112 may have a resolution in excess of 100 dpi. In an exemplary embodiment, the touch screen in the display system has a resolution of approximately 168 dpi. The user may make contact with the touch screen in thedisplay system112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which are much less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

A touch-sensitive display in some embodiments of thedisplay system112 may be as described in the following applications: (1) U.S. patent application Ser. No. 11/381,313, “Multipoint Touch Surface Controller,” filed on May 2, 2006; (2) U.S. patent application Ser.

No. 11/367,749, “Multi-Functional Hand-Held Device,” filed on Mar. 3, 2006. All of these applications are incorporated by reference herein in their entirety.

In some embodiments, in addition to the touch screen, thedevice100 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen in thedisplay system112 or an extension of the touch-sensitive surface formed by the touch screen.

In some embodiments, thedevice100 may include a physical or virtual click wheel as aninput control device116. A user may navigate among and interact with one or more graphical objects (henceforth referred to as icons) displayed in thedisplay system112 by rotating the click wheel or by moving a point of contact with the click wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the click wheel). The click wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the click wheel or an associated button. User commands and navigation commands provided by the user via the click wheel may be processed by aninput controller160 as well as one or more of the modules and/or sets of instructions inmemory102. For a virtual click wheel, the click wheel and click wheel controller may be part of thedisplay system112 and thedisplay controller156, respectively. For a virtual click wheel, the click wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual click wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen.

Thedevice100 also includes apower system162 for powering the various components. Thepower system162 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Thedevice100 may also include one or moreoptical sensors164.FIG. 1 shows an optical sensor coupled to anoptical sensor controller158 in I/O subsystem106. Theoptical sensor164 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Theoptical sensor164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with animaging module143, theoptical sensor164 may capture still images or video. In some embodiments, an optical sensor is located on the back of thedevice100, opposite thetouch screen display112 on the front of the device, so that the touch screen display may be used as a viewfinder for either still and/or video image acquisition. In some embodiments, an optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In some embodiments, the position of theoptical sensor164 can be changed by the user (e.g., by rotating the lens and the sensor in the device housing) so that a singleoptical sensor164 may be used along with the touch screen display for both video conferencing and still and/or video image acquisition.

Thedevice100 may also include one ormore proximity sensors166.FIG. 1 shows aproximity sensor166 coupled to theperipherals interface118. Alternately, theproximity sensor166 may be coupled to aninput controller160 in the I/O subsystem106. Theproximity sensor166 may perform as described in U.S. patent application Ser. No. 11/241,839, “Proximity Detector In Handheld Device,” filed Sep. 30, 2005, and U.S. patent application Ser. No. 11/240,788, “Proximity Detector In Handheld Device,” filed Sep. 30, 2005, which are hereby incorporated by reference herein in their entirety. In some embodiments, the proximity sensor turns off and disables thetouch screen112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call). In some embodiments, the proximity sensor keeps the screen off when the device is in the user's pocket, purse, or other dark area to prevent unnecessary battery drainage when the device is a locked state.

In some embodiments, the software components stored inmemory102 may include anoperating system126, a communication module (or set of instructions)128, a contact/motion module (or set of instructions)130, a graphics module (or set of instructions)132, a text input module (or set of instructions)134, a Global Positioning System (GPS) module (or set of instructions)135, and applications (or set of instructions)136.

The operating system126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Thecommunication module128 facilitates communication with other devices over one or moreexternal ports124 and also includes various software components for handling data received by theRF circuitry108 and/or theexternal port124. The external port124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Computer, Inc.) devices.

The contact/motion module130 may detect contact with the touch screen in the display system112 (in conjunction with the display controller156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The contact/motion module130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred, determining if there is movement of the contact and tracking the movement across the touch screen in thedisplay system112, and determining if the contact has been broken (i.e., if the contact has ceased). Determining movement of the point of contact may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, the contact/motion module130 and thedisplay controller156 also detects contact on a touchpad. In some embodiments, the contact/motion module130 detects movement of one or more objects on or near the touch screen and/or the touchpad. In some embodiments, the contact/motion module130 and thecontroller160 detects contact on aclick wheel116.

Thegraphics module132 includes various known software components for rendering and displaying graphics on thedisplay system112, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

Thetext input module134, which may be a component ofgraphics module132, provides soft keyboards for entering text in various applications (e.g.,contacts137,e-mail140,IM141, blogging142,browser147, and any other application that needs text input).

TheGPS module135 determines the location of the device and provides this information for use in various applications (e.g., to telephone138 for use in location-based dialing, tocamera143 and/orblogger142 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

Each of the above identified modules and applications correspond to a set of instructions for performing one or more functions described above. These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules may be combined or otherwise re-arranged in various embodiments. In some embodiments,memory102 may store a subset of the modules and data structures identified above. Furthermore,memory102 may store additional modules and data structures not described above.

In some embodiments, thedevice100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen in thedisplay system112 and/or a touchpad. By using a touch screen and/or a touchpad as the primary input/control device for operation of thedevice100, the number of physical input/control devices (such as push buttons, dials, and the like) on thedevice100 may be reduced.

The predefined set of functions that may be performed exclusively through a touch screen and/or a touchpad includes navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates thedevice100 to a main, home, or root menu from any user interface that may be displayed on thedevice100. In such embodiments, the touchpad may be referred to as a “menu button.” In some other embodiments, the menu button may be a physical push button or other physical input/control device instead of a touchpad.

FIG. 2 illustrates aportable multifunction device100 having atouch screen112 in accordance with some embodiments. The touch screen may display one or more graphics. In this embodiment, as well as others described below, a user may select one or more of the graphics by making contact or touching the graphics, for example, with one or more fingers202 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the contact may include a gesture, such as one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with thedevice100. In some embodiments, inadvertent contact with a graphic may not select the graphic. For example, a swipe gesture that sweeps over an application icon may not select the corresponding application when the gesture corresponding to selection is a tap.

Thedevice100 may also include one or more physical buttons, such as “home” ormenu button204. As described previously, themenu button204 may be used to navigate to anyapplication136 in a set of applications that may be executed on thedevice100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI intouch screen112.

In one embodiment, thedevice100 includes atouch screen112, amenu button204, apush button206 for powering the device on/off and locking the device, and volume adjustment button(s)208. Thepush button206 may be used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, thedevice100 also may accept verbal input for activation or deactivation of some functions through themicrophone113.

Attention is now directed towards embodiments of user interfaces (“UI”) and associated processes that may be implemented on aportable multifunction device100 and/or on adevice1700 with a touch-screen display (FIG. 17).

FIG. 3 illustrates an exemplary user interface for unlocking a portable electronic device in accordance with some embodiments. In some embodiments,user interface300 includes the following elements, or a subset or superset thereof:

Unlockimage302 that is moved with a finger gesture to unlock the device;

Arrow304 that provides a visual cue to the unlock gesture;

Channel306 that provides additional cues to the unlock gesture;

Time308;

Day310;

Date312; and

Wallpaper image314.

In some embodiments, the device detects contact with the touch-sensitive display (e.g., a user's finger making contact on or near the unlock image302) while the device is in a user-interface lock state. The device moves theunlock image302 in accordance with the contact. The device transitions to a user-interface unlock state if the detected contact corresponds to a predefined gesture, such as moving the unlock image acrosschannel306. Conversely, the device maintains the user-interface lock state if the detected contact does not correspond to the predefined gesture. As noted above, processes that use gestures on the touch screen to unlock the device are described in U.S. patent application Ser. No. 11/322,549, “Unlocking a Device by Performing Gestures on an Unlock Image,” filed Dec. 23, 2005, which is hereby incorporated by reference herein in its entirety.

FIG. 4 illustrates an exemplary user interface for a menu of applications on a portable multifunction device in accordance with some embodiments. In some embodiments,user interface400 includes the following elements, or a subset or superset thereof:

Signal strength indicator402 for wireless communication;

Time404;

Battery status indicator406;

Tray408 with icons for frequently used applications, such as one or more of the following:

• • Phone138;
  • E-mail client140, which may include anindicator410 of the number of unread e-mails;
  • Browser147; and
  • Music player146; and

Icons for other applications, such as one or more of the following:

  • Stocks149-2;
  • Blog142;
  • Calendar148;
  • Calculator149-3;
  • Alarm clock149-4;
  • Dictionary149-5; and
  • User-created widget149-6.

In some embodiments,UI400 displays all of theavailable applications136 on one screen so that there is no need to scroll through a list of applications (e.g., via a scroll bar or via a swipe gesture). In some embodiments, as the number of applications increases, the icons corresponding to the applications may decrease in size so that all applications may be displayed on a single screen without scrolling. In some embodiments, having all applications on one screen and a menu button enables a user to access any desired application with at most two inputs, such as activating themenu button204 and then activating the desired application (e.g., by a tap or other finger gesture on the icon corresponding to the application).

In some embodiments,UI400 provides integrated access to both widget-based applications and non-widget-based applications. In some embodiments, all of the widgets, whether user-created or not, are displayed inUI400. In other embodiments, activating the icon for user-created widget149-6 may lead to another UI (not shown) that contains the user-created widgets or icons corresponding to the user-created widgets.

In some embodiments, a user may rearrange the icons inUI400, e.g., using processes described in U.S. patent application Ser. No. 11/459,602, “Portable Electronic Device With Interface Reconfiguration Mode,” filed Jul. 24, 2006, which is hereby incorporated by reference herein in its entirety. For example, a user may move application icons in and out oftray408 using finger gestures.

In some embodiments,UI400 includes a gauge (not shown) that displays an updated account usage metric for an account associated with usage of the device (e.g., a cellular phone account), as described in U.S. patent application Ser. No. 11/322,552, “Account Information Display For Portable Communication Device,” filed Dec. 23, 2005, which is hereby incorporated by reference herein in its entirety.

As discussed above,UI400 may display all of theavailable applications136 on one screen so that there is no need to scroll through a list of applications. However, in some embodiments a touch-sensitive display may include a GUI with one or more windows that display only a portion of a list of items (e.g., information items) or of an electronic document. In response to detecting a movement of an object on or near the touch-sensitive display, the list may be scrolled or the electronic document may be translated. Detecting the movement of the object may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (including magnitude and/or direction) of the object. Scrolling through the list or translating the document may be accelerated in response to an accelerated movement of the object. In some embodiments, the scrolling and acceleration of the scrolling, or translation and acceleration of the translation, may be in accordance with a simulation of a physical device having friction, i.e., damped motion. For example, the scrolling or translation may correspond to a simulation of a force law or equation of motion having a mass or inertial term, as well as a dissipative term. In some embodiments, the simulation may correspond to a cylinder rotating about its axis.

In some embodiments, accelerated movement of the detected object may include an accelerated movement of a point of contact followed by a breaking of the point of contact. For example, the user may make contact with the touch-sensitive display, swipe or sweep one or more of his or her fingers along the display (i.e., move and/or accelerate the point of contact), and optionally, break the point of contact with the display, i.e., move the one or more fingers away from the display. The swipe or sweep may be along a predefined axis of the touch-sensitive display or may be within a predetermined angle of a predefined direction on the touch-sensitive display. In other embodiments, the accelerated movement of the point of contact may include a first user gesture oriented along a predefined axis of the touch-sensitive display or oriented within a predetermined angle of a predefined direction on the touch-sensitive display.

Scrolling through the list of items or translating the electronic document may be further accelerated in response to detection of a second movement of an object on or near the touch-sensitive display, such as a second sweeping motion of the point of contact along the predefined axis or within the predetermined angle of a predefined direction on the touch-sensitive display and/or a second user gesture oriented along the predefined axis or within the predetermined angle of a predefined direction on the touch-sensitive display. For example, the user may swipe one or more of his or her fingers along the touch-sensitive display two or more times.

The scrolling through the list of items or the translation of the electronic document may be stopped in accordance with the user breaking the point of contact and then establishing a substantially stationary point of contact with the touch-sensitive display for at least a pre-determined period of time. For example, after swiping one or more of his or her fingers along the touch-sensitive display and breaking the point of contact, the user may touch the display and hold the one or more fingers that are touching the display stationary (or approximately stationary) for one or more seconds, or fractions of a second.

The direction of scrolling or translation may be reversed in response to intersecting a virtual boundary corresponding to a terminus of the list or an edge of the electronic document. The scrolling reversal or translation reversal may correspond to a damped motion. For example, during scrolling, a displayed portion of the list of items may appear to bounce off of a boundary of the window in the touch-sensitive display when a beginning or an end of the list of items is reached. Similarly, during translation, a displayed portion of the electronic document may appear to bounce off of a boundary of the window in the touch-sensitive display when an edge of the document is reached. The apparent bounce may correspond to a simulation of a viscous or elastic ball having momentum in a first direction striking an immovable and/or inelastic object, such as a wall. The subsequent motion of the document (the motion of which corresponds to the ball in the aforementioned analogy) may be damped, for example, by including a friction or dissipative term in the simulation. A parameter corresponding to the friction term in the simulation may be adjustable, allowing the document to reach equilibrium in contact with the virtual boundary, or displaced from the virtual boundary.

In some embodiments movement of the point of contact by the user over an index on the touch-sensitive display may be determined. In some embodiments, the index may be displayed in a first region or a first window of the touch-sensitive display while the list of items or information items during the scrolling may be displayed in a second region or a second window of the touch-sensitive display. The displayed index may have a sequence of index items. In an exemplary embodiment, the sequence of index items may include letters in the alphabet, i.e., the index may include an alphabetical index. The list of information items may include an alphabetically ordered list of information items. The alphabetically ordered list of information items may include contact information, for example, in a user's contact list or address book.

In response to movement of the user's point of contact over a displayed index, the list of information items on the touch-sensitive display may be scrolled. The list of information items may include a sequence of information item subsets corresponding to the sequence of index items. The subsets may include one or more categories. For example, a respective category may include contact information for one or more individuals whose first and/or last names begin with one or more respective letters, such as the letter ‘s’. In an exemplary embodiment, there is a subset corresponding to each letter in the alphabet that has one or more entries. In some embodiments, the scrolling may be in accordance with a simulation of an equation of motion having friction.

The scrolling may include scrolling through a respective information item subset if the point of contact moves over a corresponding respective index item in the index items. The scrolling may have an associated scroll speed based on a speed of movement of the point of contact over the respective index item and the number of items in the information item subset corresponding to the respective index item. For example, the scroll speed may be faster for subsets that have more entries than subsets with fewer entries. The scrolling may include scrolling through all items in a plurality of the information item subsets in response to the point of contact moving over the corresponding index items in the displayed index.

If it is determined that the point of contact with the index corresponds to a respective index item in the index, the list of information items may be scrolled to a corresponding subset of the list of information items. For example, if the user selects an index item, such as the letter ‘R’, in the set of index symbols, the list of items may be smoothly scrolled to the corresponding subset for the letter ‘R’ in the list of items. Alternatively, the displayed list of information items jump directly from a current scroll position to a scroll position in which information items corresponding to the index item ‘R’ are displayed.

In the present document, the term “if” may be construed to mean “when,” or “upon,” or “in response to determining,” or “in response to detecting,” depending on the context Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting” the stated condition or event, or “in response to detecting” the stated condition or event, depending on the context.

If the point of contact with the touch-sensitive display corresponds to a user selection of a respective information item in the list of information items, information corresponding to the respective information item may be displayed on the touch-sensitive display. For example, if the user selects a respective name, the corresponding contact information may be displayed.

While scrolling through respective information subsets, an index symbol may displayed in conjunction with each respective information item subset. In some embodiments, respective index symbols may be displayed adjacent to corresponding subsets (such as displayed text) of the list of information items. In some embodiments, a respective index symbol may be displayed at an upper edge of a window containing the displayed text of the respective information item subset.

The index symbol corresponding to a respective information subset may be translucently displayed over the respective information item subset. The translucently displayed index symbol may have a different font color than that used to display text in the information item subset, and/or it may be displayed using a larger font than the font used to display text in the information item subset.

If the list of information items contains no items for a particular index symbol, i.e., no entries for a particular subset, a first index symbol preceding a particular index symbol and a second index symbol following the index symbol may be displayed in conjunction with scrolling through the list of information items from the information subset corresponding to the first index symbol to the information subset corresponding to the second index symbol. The particular index symbol may not be displayed in conjunction with the displayed text of the list of information items during the scroll through. For example, display of a respective index symbol may be skipped when the list of information items contains no items for the particular index symbol.

In some embodiments, the list scrolling described here operates without displaying a scroll bar. Similarly, in some embodiments, the translation of electronic documents described here operates without displaying scroll bars. The user's sweeping motion on the touch-sensitive display operation may be performed directly on top of the displayed list or displayed electronic document, and may include a sweeping or gliding motion, near or in contact with the display's surface, along a path anywhere within a display window in which the list or electronic document is displayed. While a scroll bar could potentially be displayed in conjunction with the displayed list, the scrolling or translation described here can be independent of any such scroll bar. In some embodiments, if a scroll bar is used, then an upward movement of a point of contact on the scroll bar may cause earlier entries in the list to be displayed, whereas a downward movement of the point of contact on the scroll bar may cause later entries in the list to be displayed.

In some embodiments, scrolling or translation may be in accordance with a speed of movement of a detected object, such as a speed of movement of a point of contact. The speed may be a time average of values determined during several time intervals. In an exemplary embodiment, the speed, velocity and/or acceleration may be determined over five time intervals, where a respective time interval corresponds to an inverse of a frame rate, such as 0.0167 s, of a display. In some embodiments, the speed, velocity and/or acceleration may be determined even when a variable frame rate is used, such as when one or more frames are skipped or not displayed. In these embodiments, the speed, velocity, and/or acceleration may be determined two or more times for the respective time interval and/or may be projected based on values determined in a preceding and/or a subsequent time interval.

In some embodiments, the scrolling or translation after a user optionally breaks the contact may be in accordance with the change in the acceleration and the speed or the velocity in one or more time intervals prior to the breaking of the contact. For example, the velocity v_fof scrolling or translation one or more time intervals after breaking contact may be determined using
v_f=v_o+αΔt,
where v_ois a current value of the velocity when the contact is broken, a is a current value of the acceleration when the contact is broken and Δt is an elapsed time, such as one time interval. The velocities and/or acceleration in such a calculation may be projected along an axis or direction of the scrolling or translation. In some embodiments, in subsequent time intervals following the determination of the velocity based on the acceleration and/or the velocity in one or more time intervals prior to the breaking of the contact, the velocity of the scrolling or translation may be tapered. For example, in each successive time interval the velocity may be decreased by 5%. When the velocity crosses a lower threshold, it may be set to zero.

FIG. 5 is a flow diagram illustrating amethod500 of scrolling through a list in accordance with some embodiments. Themethod500 provides a simple visual indicator to a user that a terminus of a list has been reached.

Movement of an object is detected on or near a touch screen display of a device (502). In some embodiments, the object is a finger. In some embodiments, the device is a portable multifunction device.

In response to detecting the movement, a list of items displayed on the touch screen display is scrolled in a first direction (504). In some embodiments, the list is a list of email messages, as illustrated inFIGS. 6A-6D. In some embodiments, the list of items is a list of instant message conversations, a list of favorite phone numbers, a list of contact information (sometimes called a contact list or address book list), a list of labels, a list of email folders, a list of email addresses, a list of physical addresses, a list of ringtones, a list of album names, or a list of bookmarks. In some embodiments, the first direction is a vertical direction; in some other embodiments, the first direction is a horizontal direction. In some embodiments, scrolling the list in the first direction prior to reaching a terminus of the list has an associated scrolling speed corresponding to a speed of movement of the object (506). In some embodiments, the list is scrolled in accordance with a simulation of an equation of motion having friction (508).

If a terminus of the list is reached (e.g., upon reaching the terminus of the list) while scrolling the list in the first direction while the object is still detected on or near the touch screen display, an area beyond the terminus of the list is displayed (510-Yes,514). In some embodiments, the list has a first item and a last item and the terminus is either the first item or the last item. For example, inFIG. 6B theemail3534 from Aaron Jones is the first item and thus the terminus of the corresponding list of emails. In some embodiments, the area beyond the terminus of the list is white (516). In some embodiments, the list of items has a background and the area beyond the terminus of the list is visually indistinct from the background (518). For example, inFIG. 6C both thearea3536 and the background of the listed emails are white.

After the object is no longer detected on or near the touch screen display, the list of items is scrolled in a second direction opposite the first direction until the area beyond the terminus of the list is no longer displayed (520). In some embodiments, the list is scrolled in the second direction using a damped motion (522). In some embodiments, the change from scrolling the list in the first direction to scrolling the list in the second direction until the area beyond the terminus of the list is no longer displayed makes the terminus of the list appear to be elastically attached to an edge of the touch screen display or to an edge displayed on the touch screen display (524).

In some embodiments, scrolling in the first direction prior to reaching the terminus of the list has a first associated scrolling distance that corresponds to a distance of movement of the object prior to reaching the terminus of the list. For example, a scrolling distance prior to reaching the terminus of the list shown inFIGS. 6A-6D may correspond to a distance traversed on the touch screen display by theswipe gesture3514 before the terminus is reached. Displaying an area beyond the terminus of the list includes scrolling the list in the first direction for a second associated scrolling distance that is less than a distance of movement of the object after the terminus is reached. For example, inFIG. 6C, after the terminus is reached the list is scrolled for adistance3538, which may be less than a distance traversed on the touch screen display by theswipe gesture3514 after the terminus is reached.

In some embodiments, scrolling in the first direction prior to reaching a terminus of the list has a first associated scrolling speed that corresponds to a speed of movement of the object. For example, a scrolling speed prior to reaching the terminus of the list shown inFIGS. 6A-6D may correspond to a speed on the touch screen display of theswipe gesture3514 before the terminus is reached. Displaying an area beyond the terminus of the list includes scrolling the list in the first direction at a second associated scrolling speed. The second associated scrolling speed is slower than the first associated scrolling speed. For example, inFIG. 6C, displaying thearea3536 beyond the terminus of the list may include scrolling the list at a speed that is slower than the scrolling speed before the terminus is reached. In some embodiments, the second associated speed is a fraction (e.g., one-half or one-third) of the first associated speed. In some embodiments, the second associated speed is the square root of the first associated speed.

If a terminus of the list is not reached while scrolling the list in the first direction while the object is still detected on or near the touch screen display, theprocess500 is complete (510-No,512). Theprocess500 may be re-initiated upon subsequent detection of another movement of an object on or near the touch screen display (502).

FIGS. 6A-6D illustrate the scrolling of a list of items to a terminus of the list, at which point an area beyond the terminus is displayed and the list is then scrolled in an opposite direction until the area beyond the terminus is no longer displayed, in accordance with some embodiments. WhileFIGS. 6A-6D illustrate this scrolling in the context of aportable multifunction device100, this scrolling is not limited to portable multifunction devices. In the example ofFIGS. 6A-6D, the listed items are email messages;FIGS. 6A-6D illustrate anexemplary user interface3500A for managing an inbox in accordance with some embodiments. An analogous user interface may be used to display and manage other mailboxes (e.g., drafts, sent, trash, personal, etc.). In addition, other types of lists are possible, including but not limited to lists of instant message conversations, favorite phone numbers, contact information, labels, email folders, email addresses, physical addresses, ringtones, album names or bookmarks.

In some embodiments,user interface3500A include the following elements, or a subset or superset thereof:

402,404, and406, as described above;

a createemail icon3310 that when activated (e.g., by a finger tap on the icon) initiates display of a UI to create a new email message;

mailboxes icon3502 that when activated (e.g., by a finger tap on the icon) initiates the display of a UI listing email mailboxes (i.e., folders);

unread messages icon3504 that displays the number of unread messages in the inbox;

names3506 of the senders of the email messages;

subject lines3508 for the email messages;

dates3510 of the email messages;

unread message icons3512 that indicate messages that have not been opened;

preview pane separator3518 that separates the list of messages from a preview of a selected message in the list;

settings icon3520 that when activated (e.g., by a finger tap on the icon) initiates the display of a UI to modify settings;

movemessage icon3522 that when activated (e.g., by a finger tap on the icon) initiates the display of a UI to move messages;

Delete symbol icon3524 that when activated (e.g., by a finger tap on the icon) initiates display of a UI to confirm that the user wants to delete the selected email;

Reply/Forward icon3526 that when activated (e.g., by a finger tap on the icon) initiates display of a UI to select how to reply or forward the selected email;

If the list of emails fills more than the allotted screen area, the user may scroll through the emails using vertically upward and/or vertically downward swipe gestures on the touch screen. In the example ofFIG. 6A, a portion of a list of emails is displayed in the screen area, including a top displayedemail3530 from Bruce Walker and a bottom displayedemail3532 from Kim Brook. A user performs a verticallydownward swipe gesture3514 to scroll toward the top of the list. The verticallydownward gesture3514, which may be a finger gesture, corresponds to the movement of an object on or near the touch screen that is detected inoperation502 of process500 (FIG. 5). The verticallydownward gesture3514 need not be exactly vertical; a substantially vertical gesture is sufficient. In some embodiments, a gesture within a predetermined angle of being perfectly vertical results in vertical scrolling. In one embodiment, a gesture within 27 degrees of being perfectly vertical results in vertical scrolling.

As a result of detecting the verticallydownward gesture3514, inFIG. 6B the displayed emails have shifted down, such that the previous bottom displayedemail3532 from Kim Brook is no longer displayed, the previous top displayedemail3530 from Bruce Walker is now second from the top, and theemail3534 from Aaron Jones, which was not displayed inFIG. 6A, is now displayed at the top of the list. This shifting of emails is an example of the scrolling described inoperation504 of process500 (FIG. 5).

In this example, theemail3534 from Aaron Jones is the first email in the list and thus is the terminus of the list. Upon reaching thisemail3534, in response to continued detection of the verticallydownward gesture3514, an area3536 (FIG. 6C) above the first email3534 (i.e., beyond the terminus of the list) is displayed, as described inoperation514 of process500 (FIG. 5). In some embodiments, the area displayed beyond the terminus of the list is visually indistinct from the background of the list, as described inoperation518 of process500 (FIG. 5). InFIG. 6C, both thearea3536 and the background of the emails (e.g.,emails3534 and3530) are white and thus are visually indistinct.

Once verticallydownward gesture3514 is complete, such that a corresponding object is no longer detected on or near the touch screen display, the list is scrolled in an opposite direction until thearea3536 is no longer displayed.FIG. 6D illustrates the result of this scrolling in the opposite direction, which corresponds tooperation520 of process500 (FIG. 5): theemail3534 from Aaron Jones is now displayed at the top of the screen area allotted to the list and thearea3536 is not displayed.

In the example ofFIGS. 6A-6D, a vertically downward gesture resulted in display of an area beyond the first item in the list. Similarly, a vertically upward gesture may result in display of an area beyond the last item of the list, if the vertically upward gesture continues once the list has been scrolled to the last item. The last item may be considered a terminus of the list, similar to the first item. As discussed above, the gesture need not be exactly vertical to result in vertical scrolling; a gesture within a predefined range of angles from perfectly vertical is sufficient.

In some embodiments, instead of scrolling a list of items in one dimension, a user may desire to translate an electronic document in two dimensions. If the electronic document fills more than the screen area allotted to display the document, the screen will only display a portion of the document. The user may translate the electronic document to view portions of the document that are not initially displayed.

FIG. 7 is a flow diagram illustrating amethod700 of translating an electronic document in accordance with some embodiments. Themethod700 provides a simple visual indicator to a user that one or more edges of an electronic document are being displayed.

Movement of an object is detected on or near a touch screen display of a device (702). In some embodiments, the object is a finger. In some embodiments, the device is a portable multifunction device.

In response to detecting the movement, an electronic document displayed on the touch screen display is translated in a first direction (704). In some embodiments, the electronic document is a web page, as illustrated inFIGS. 8A-8D. In some embodiments, the electronic document is a digital image. In some embodiments, the electronic document is a word processing, spreadsheet, email, or presentation document. In some embodiments, the first direction is a vertical direction, a horizontal direction, or a diagonal direction. In some embodiments, the first direction corresponds to the direction of movement of the object detected on or near the display but is not necessarily identical to the direction of movement of the object.

In some embodiments, translating the electronic document in the first direction prior to reaching an edge of the electronic document has an associated speed of translation corresponding to a speed of movement of the object (706). In some embodiments, the electronic document is translated in accordance with a simulation of an equation of motion having friction (708).

If an edge of the electronic document is reached (e.g., upon reaching the edge of the document) while translating the electronic document in the first direction while the object is still detected on or near the touch screen display, an area beyond the edge of the electronic document is displayed (710-Yes,714). In some embodiments, the area beyond the edge of the electronic document is black, gray, a solid color, or white (716). In some embodiments, the area beyond the edge of the electronic document is visually distinct from the document (718). For example, thearea3930 beyond the edge of theweb page3912 inFIG. 8C is black, in contrast to the white background of theweb page3912. In some other embodiments, a wallpaper image such as a picture or pattern may be displayed in the area beyond the edge of the electronic document.

After the object is no longer detected on or near the touch screen display, the electronic document is translated in a second direction until the area beyond the edge of the electronic document is no longer displayed (720). For example, inFIG. 8D theweb page3912 has been translated such that thearea3930 beyond its edge is no longer displayed. In some embodiments, the second direction is opposite the first direction. In some embodiments, the electronic document is translated in the second direction using a damped motion (722). In some embodiments, the change from translating the electronic document in the first direction to translating the electronic document in the second direction until the area beyond the edge of the electronic document is no longer displayed makes the edge of the electronic document appear to be elastically attached to an edge of the touch screen display or to an edge displayed on the touch screen display (724).

In some embodiments, translating in the first direction prior to reaching an edge of the electronic document has a first associated translating distance that corresponds to a distance of movement of the object prior to reaching the edge of the electronic document. For example, a distance of translation of theweb page3912 shown inFIGS. 8A-8D prior to reaching the edge of the document may correspond to a distance traversed on the touch screen display by theswipe gesture3925 before the edge is reached. In some embodiments, displaying an area beyond the edge of the electronic document includes translating the electronic document in the first direction for a second associated translating distance, wherein the second associated translating distance is less than a distance of movement of the object after reaching the edge of the electronic document. For example, inFIG. 8C, after the edge is reached theweb page3912 is translated by a distance indicated by opposing arrows3928-1 and3928-2, which may be less than a distance traversed on the touch screen display by theswipe gesture3925 after the terminus is reached.

In some embodiments, translating in the first direction prior to reaching an edge of the electronic document has a first associated translating speed that corresponds to a speed of movement of the object. For example, a speed of translation prior to reaching the edge of theweb page3912 shown inFIGS. 8A-8D may correspond to a speed of movement of theswipe gesture3925. Displaying an area beyond the edge of the electronic document includes translating the electronic document in the first direction at a second associated translating speed. The second associated translating speed is slower than the first associated translating speed. For example, inFIG. 8C, displaying thearea3930 beyond the edge of theweb page3912 may include translating theweb page3912 at a speed that is slower than the speed of translation before the edge is reached. In some embodiments, the second associated speed is a fraction (e.g., one-half or one-third) of the first associated speed. In some embodiments, the second associated speed is the square root of the first associated speed.

If an edge of the electronic document is not reached while translating the electronic document in the first direction while the object is still detected on or near the touch screen display, theprocess700 is complete (710-No,712). Theprocess700 may be re-initiated upon subsequent detection of another movement of an object on or near the touch screen display (702).

FIGS. 8A-8D illustrate the translation of an electronic document to an edge of the document, at which point an area beyond the edge is displayed and the document is then translated in a second direction until the area beyond the edge of the document is no longer displayed, in accordance with some embodiments. WhileFIGS. 8A-8D illustrate this translation in the context of aportable multifunction device100, this translation is not limited to portable multifunction devices. In the example ofFIGS. 8A-8D, the document is aweb page3912;FIGS. 8A-8D illustrate an exemplary user interface for a browser in accordance with some embodiments. An analogous user interface may be used to display other types of electronic documents, such as word processing, spreadsheet, email, presentation documents, or digital images.

In some embodiments,user interface3900A ofFIGS. 8A-8D includes the following elements, or a subset or superset thereof:

402,404, and406, as described above;

Previous page icon3902 that when activated (e.g., by a finger tap on the icon) initiates display of the previous web page;

Web page name3904;

Next page icon3906 that when activated (e.g., by a finger tap on the icon) initiates display of the next web page;

URL (Uniform Resource Locator)entry box3908 for inputting URLs of web pages;

Refresh icon3910 that when activated (e.g., by a finger tap on the icon) initiates a refresh of the web page;

Web page3912 or other structured document, which is made ofblocks3914 of text content and other graphics (e.g., images);

Settings icon3916 that when activated (e.g., by a finger tap on the icon) initiates display of a settings menu for the browser;

Bookmarks icon3918 that when activated (e.g., by a finger tap on the icon) initiates display of a bookmarks list or menu for the browser;

Addbookmark icon3920 that when activated (e.g., by a finger tap on the icon) initiates display of a UI for adding bookmarks; and

New window icon3922 that when activated (e.g., by a finger tap on the icon) initiates display of a UI for adding new windows to the browser.

In some embodiments, the device analyzes the render tree of theweb page3912 to determine theblocks3914 in the web page. In some embodiments, ablock3914 corresponds to a render node that is: replaced; a block; an inline block; or an inline table.

InFIG. 8A, the web page fills more than the allotted screen area: only the left sides of block7 (3914-7) and block8 (3914-8) are displayed and only the top left corner of block9 (3914-9) is displayed. To view the partially displayed blocks, a user may translate the displayed document by gesturing on the touch screen in accordance with some embodiments.

In some embodiments, in response to a substantially vertical upward (or downward) swipe gesture by the user, the web page (or, more generally, other electronic documents) may translate one-dimensionally upward (or downward) in the vertical direction. In some embodiments, a gesture is considered substantially vertical if it is within a predetermined angle of being perfectly vertical. For example, in response to an upward swipe gesture by the user that is within a predetermined angle (e.g., 27°) of being perfectly vertical, the web page may scroll one-dimensionally upward in the vertical direction.

Conversely, in some embodiments, in response to a gesture that is not within a predetermined angle (e.g., 27°) of being perfectly vertical, the web page may translate two-dimensionally (i.e., with simultaneous movement in both the vertical and horizontal directions). For example, in response to an upward swipe gesture by the user that is not within a predetermined angle (e.g., 27°) of being perfectly vertical, the web page may translate two-dimensionally along the direction of the swipe.

In the example ofFIG. 8A, anupward swipe gesture3925 is not within a predetermined angle of being perfectly vertical. Therefore, as a result of detecting theupward swipe gesture3925, the web page is translated in two dimensions. In this example, the translation is approximately diagonal.FIG. 8B illustrates the result of this translation: blocks8 (3914-8) and9 (3914-9) are now fully displayed; blocks1 (3914-1) and2 (3914-2) are now only partially displayed, and block3 (3914-3) is no longer displayed at all. This translation is an example of the translation described inoperation704 of process700 (FIG. 7).

InFIG. 8B, block9 (3914-9) is in the lower right-hand corner of theweb page3912; both the bottom and right edges of the web page have been reached while translating the web page. Upon reaching these edges of the document, in response to continued detection of theupward gesture3925, an area3930 (FIG. 8C) beyond the bottom and right edges of the web page is displayed. In some embodiments, the area displayed beyond the edge(s) of an electronic document is visually distinct from the document, as described inoperation718 of process700 (FIG. 7). InFIG. 8C, thearea3930 is black and thus is visually distinct from the white background of theweb page3912.

Once theupward gesture3925 is complete, such that a corresponding object is no longer detected on or near the touch screen display, theweb page3912 is translated (e.g., in a direction opposite to the original direction of translation) until thearea3930 is no longer displayed.FIG. 8D illustrates the result of this translation, which corresponds tooperation720 of process700 (FIG. 7): block9 (3914-9) is now displayed in the lower right-hand corner of the portion of the screen allotted to display theweb page3912 and thearea3930 not displayed. In some embodiments, the direction of translation is not necessarily opposite to the original direction but may be in any direction such that, upon completion of the translation, the area beyond the edge(s) of the electronic document is no longer displayed.

FIG. 9 is a flow diagram illustrating aprocess900 of displaying an electronic document having a document length and a document width, in accordance with some embodiments. Theprocess900 provides a simple visual indicator to a user that an electronic document is being displayed at a minimum magnification (e.g., the electronic document cannot be zoomed out and/or demagnified further).

Theprocess900 is performed at a device with a touch screen display. In some embodiments, the device is a portable multifunction device. In some embodiments, the electronic document is a web page (e.g.,web page3912,FIGS. 10A-10C). In some embodiments, the electronic document is a digital image. In some embodiments, the electronic document is a word processing, spreadsheet, email or presentation document.

The electronic document is displayed (902) at a first magnification on the touch screen display. A gesture is detected (904) on or near the touch screen display corresponding to a command to zoom out by a user-specified amount. In some embodiments, the gesture is a pinching gesture (e.g.,gesture3951/3953,FIG. 10A).

In response to detecting the gesture, the electronic document is displayed (906) at a magnification less than the first magnification. For example, theweb page3912 is shown at a lesser magnification inFIG. 10B than inFIG. 10A.

If the document length or document width is not entirely displayed (908-No) while the gesture is still detected on or near the touch screen display, theprocess900 is complete (910).

If, however, the document length (e.g.,3957,FIG. 10B) or document width (e.g.,3959,FIG. 10B) is entirely displayed (908-Yes) while the gesture (e.g.,3951/3953) is still detected on or near the touch screen display, the electronic document is displayed (912) at a magnification wherein areas beyond opposite edges of the electronic document (e.g.,areas3955,FIG. 10B) are displayed.

In some embodiments, the areas beyond opposite edges of the electronic document include an area beyond a top edge of the document and an area beyond a bottom edge of the document. In some embodiments, the areas beyond opposite edges of the electronic document include an area beyond a right edge of the document and an area beyond a left edge of the document. In some embodiments, the areas beyond opposite edges of the electronic document include an area beyond a top edge of the document, an area beyond a bottom edge of the document, an area beyond a right edge of the document, and an area beyond a left edge of the document (e.g.,FIG. 10B).

In some embodiments, the areas beyond opposite edges of the electronic document are black, gray, a solid color, or white. In some embodiments, the areas beyond opposite edges of the electronic document are visually distinct from the document. For example, the areas3955 (FIG. 10B) are black and thus are visually distinct from theweb page3912.

Upon detecting termination of the gesture, the electronic document is displayed (914) at a magnification wherein the areas beyond opposite edges of the electronic document are no longer displayed. For example, theareas3955 are not displayed inFIG. 10C.

FIGS. 10A-10C illustrate the display of an electronic document at multiple magnifications in accordance with some embodiments. WhileFIGS. 10A-10C illustrate displaying these multiple magnifications in the context of aportable multifunction device100, displaying these multiple magnifications is not limited to portable multifunction devices. In the example ofFIGS. 10A-10C, the document is aweb page3912;FIGS. 10A-10C (likeFIGS. 8A-8D) illustrate an exemplary user interface for a browser in accordance with some embodiments. An analogous user interface may be used to display other types of electronic documents, such as digital images or word processing, spreadsheet, email, or presentation documents.

InFIG. 10A, theweb page3912 is displayed at a first magnification. Theweb page3912 fills more than the allotted screen area: only the left sides of block7 (3914-7) and block8 (3914-8) are displayed and only the top left corner of block9 (3914-9) is displayed.

In response to detecting apinching gesture3951/3953 (FIG. 10A), the web-page is displayed at a magnification less than the first magnification, as shown inFIG. 10B. If adocument length3957 or adocument width3959 is entirely displayed while thegesture3951/3953 is still detected,areas3955 beyond opposite edges of theweb page3912 are displayed. Upon detecting termination of thegesture3951/3953, theweb page3912 is displayed at a magnification wherein theareas3955 are no longer displayed, as shown inFIG. 10C.

FIG. 11 is a flow diagram illustrating aprocess1100 of displaying an electronic document at multiple magnifications in accordance with some embodiments. Theprocess1100 provides a simple visual indicator to a user that an electronic document is being displayed at a maximum magnification (e.g., the electronic document cannot be zoomed in and/or magnified further).

Theprocess1100 is performed at a device with a touch screen display. In some embodiments, the device is a portable multifunction device. In some embodiments, the electronic document is a web page (e.g.,web page3912,FIGS. 12A-12C). In some embodiments, the electronic document is a digital image (e.g.,digital image1302,FIGS. 13A-13C). In some embodiments, the electronic document is a word processing, spreadsheet, email or presentation document.

At least a first portion of the electronic document is displayed (1102) at a first magnification. A gesture is detected (1104) on or near the touch screen display corresponding to a command to zoom in by a user-specified amount. In some embodiments, the gesture is a de-pinching gesture (e.g.,3931/3933,FIGS. 12A and 13A).

In response to detecting the gesture, decreasing portions of the electronic document are displayed (1106) at increasing magnifications. For example, inFIG. 12B a decreased portion of theweb page3912 is displayed at a higher magnification than the portion inFIG. 12A, and inFIG. 13B a decreased portion of thedigital image1302 is displayed at a higher magnification than the portion inFIG. 13A.

If, upon detecting termination of the gesture, the magnification does not exceed a predefined magnification (1108-No), theprocess1100 is complete (1110).

If however, upon detecting termination of the gesture, the magnification exceeds a predefined magnification (1108-Yes), a respective portion of the electronic document is displayed (1112) at the predefined magnification. In the examples ofFIGS. 12B and 13B, the magnification exceeds a predefined magnification. Upon detecting termination of thegesture3931/3933, a portion of theweb page3912 is displayed at the predefined magnification, as illustrated inFIG. 12C, and a portion of thedigital image1302 is displayed at the predefined magnification, as illustrated inFIG. 13C.

In some embodiments, immediately prior to detecting termination of the gesture, a last decreased portion of the electronic document is displayed at a first resolution. Upon detecting termination of the gesture, the respective portion of the electronic document is displayed at a second resolution that is greater than the first resolution.

FIGS. 12A-12C illustrate the display of an electronic document at multiple magnifications in accordance with some embodiments. WhileFIGS. 12A-12C illustrate displaying these multiple magnifications in the context of aportable multifunction device100, displaying these multiple magnifications is not limited to portable multifunction devices. In the example ofFIGS. 12A-12C, the document is aweb page3912;FIGS. 12A-12C (likeFIGS. 8A-8D) illustrate an exemplary user interface for a browser in accordance with some embodiments. An analogous user interface may be used to display other types of electronic documents, such as digital images or word processing, spreadsheet, email, or presentation documents.

InFIG. 12A, a first portion of theweb page3912 is displayed at a first magnification. Theweb page3912 fills more than the allotted screen area: only the left sides of block7 (3914-7) and block8 (3914-8) are displayed and only the top left corner of block9 (3914-9) is displayed.

In response to detecting ade-pinching gesture3931/3933 (FIG. 12A), decreasing portions of the web-page3912 are displayed at increasing magnifications compared to the magnification shown inFIG. 12A. For example, the portion of theweb page3912 shown inFIG. 12B is smaller than and has a higher magnification than the portion of theweb page3912 shown inFIG. 12A.

In the example ofFIG. 12B, the magnification exceeds a predefined magnification. Upon detecting termination of thegesture3931/3933, a portion of theweb page3912 is displayed at the predefined magnification, as illustrated inFIG. 12C.

FIGS. 13A-13C illustrate the display of an electronic document at multiple magnifications in accordance with some embodiments. WhileFIGS. 13A-13C illustrate displaying these multiple magnifications in the context of aportable multifunction device100, displaying these multiple magnifications is not limited to portable multifunction devices. In the example ofFIGS. 13A-13C, the document is adigital image1302 that includes an image of aperson1304.

InFIG. 13A, adigital image1302 is displayed at a first magnification. In response to detecting ade-pinching gesture3931/3933, decreasing portions of thedigital image1302 are displayed at increasing magnifications compared to the magnification shown inFIG. 13A. For example, the portion of thedigital image1302 shown inFIG. 13B is smaller than and has a higher magnification than the portion of thedigital image1302 shown inFIG. 13A.

In the example ofFIG. 13B, the magnification exceeds a predefined magnification. Upon detecting termination of thegesture3931/3933, a portion of thedigital image1302 is displayed at the predefined magnification, as illustrated inFIG. 13C.

FIG. 14 is a flow diagram illustrating aprocess1400 of executing a screen rotation command in accordance with some embodiments. Theprocess1400 provides a simple visual indicator to a user that the user has not provided a sufficient gesture to initiate a 90° screen rotation command.

Theprocess1400 is performed at a device with a touch screen display. In some embodiments, the device is a portable multifunction device.

A multifinger twisting gesture (e.g.,1506,FIG. 15A, or1508,FIG. 15C) is detected (1402) on or near the touch screen display. The multifinger twisting gesture has a corresponding degree of rotation. In some embodiments, the multifinger twisting gesture includes gestures by two thumbs1604-L and1604-R (FIGS. 16A and 16D)

If the corresponding degree of rotation exceeds a predefined degree of rotation (1404-Yes), a 90° screen rotation command is executed (1406). For example, thedigital image1502 ofFIGS. 15A and 16A is rotated from a portrait orientation to a landscape orientation, as shown respectively inFIGS. 15B and 16B.

If the corresponding degree of rotation does not exceed a predefined degree of rotation (1404-No), a screen rotation command with an acute angle of rotation (i.e., less than 90°) is executed (1408). For example, thedigital image1502 ofFIGS. 15C and 16D is rotated by an acute angle, as shown respectively inFIGS. 15D and 16E. Upon ceasing to detect the multi finger twisting gesture, a screen rotation command is executed (1410) with an angle of rotation opposite to the acute angle (e.g., with the result shown inFIGS. 15E and 16F).

FIGS. 15A-15E illustrate rotating the display of an electronic document or other digital object in accordance with some embodiments. WhileFIGS. 15A-15E illustrate display rotation in the context of aportable multifunction device100, display rotation is not limited to portable multifunction devices. In the example ofFIGS. 15A-15E, the electronic document is adigital image1502.

InFIGS. 15A and 15C, thedigital image1502 is displayed in a portrait orientation. A multifinger twisting gesture1506 (FIG. 15A) or1508 (FIG. 15C) is detected on the touch screen display. Themultifinger twisting gesture1506 or1508 has a corresponding degree of rotation. In some embodiments, the degree of rotation corresponds to a degree of rotation of an axis between the contact points on the touch screen display of the two fingers in the multifinger gesture (e.g., an axis between the center points or centroids of the contact regions of the two fingers).

In the example ofFIG. 15A, themultifinger twisting gesture1506 has a corresponding degree of rotation that exceeds a predefined degree of rotation. Thus, a 90° screen rotation command is executed, with the result that the digital image is displayed in a landscape orientation, as shown inFIG. 15B. In the example ofFIG. 15C, however, themultifinger twisting gesture1508 has a corresponding degree of rotation that does not exceed a predefined degree of rotation. A screen rotation command with an acute angle of rotation is executed, with the result shown inFIG. 15D. Upon ceasing to detect themultifinger twisting gesture1508, a screen rotation command with an angle opposite to the acute angle is executed, with the result that the portrait orientation of thedigital image1502 is restored, as shown inFIG. 15E.

FIGS. 16A-16F illustrate an exemplary screen rotation gesture in accordance with some embodiments. WhileFIGS. 16A-16F illustrate this screen rotation gesture in the context of aportable multifunction device100, this screen rotation gesture is not limited to portable multifunction devices. In the example ofFIGS. 16A-16F, this screen rotation gesture is used to rotate thedigital image1502.

InFIG. 16A, thedevice100 displays thedigital image1502 in a portrait orientation. Simultaneous rotation of two thumbs (e.g.,1604-L and1604-R) in a first sense of rotation is detected on thetouch screen display112. In some embodiments, the first sense of rotation is a clockwise rotation (e.g.,FIG. 16C). The simultaneous rotation of the two thumbs has a corresponding degree of rotation.

In some embodiments, the sense of rotation for each thumb is detected by monitoring the change in orientation of the contact area of the thumb with the touch screen display. For example, if the contact area of the thumb is elliptical, the change in the orientation of an axis of the ellipse may be detected (e.g., from contact ellipse1606-L inFIG. 16A to contact ellipse1608-L inFIG. 16B, as shown on an enlarged portion oftouch screen112 inFIG. 16C). In some embodiments, the change in the orientation of the axis of the ellipse determines the corresponding degree of rotation. In some embodiments, at least some of a user's other fingers (i.e., fingers other than thumbs1604-L and1604-R) support thedevice100 by contacting the backside of the device.

In some embodiments, the first sense of rotation is a counterclockwise rotation. For example, if thumb1604-L is initially on the lower left side of touch screen112 (rather than the upper left side inFIG. 16A), thumb1604-R is initially on the upper right side of touch screen112 (rather than the lower right side inFIG. 16A), and the thumbs are moved apart from each other, then the sense of rotation detected by thetouch screen112 will be counterclockwise for both thumbs.

If the corresponding degree of rotation exceeds a predefined degree of rotation, a 90° screen rotation command is executed. For example, display of thedigital image1502 is rotated from the portrait orientation ofFIG. 16A to a landscape orientation inFIG. 16B.

If, however, the corresponding degree of rotation does not exceed a predefined degree of rotation, a screen rotation command with an acute angle of rotation is executed. For example, thedigital image1502 inFIG. 16D is rotated by an acute angle, with the result shown inFIG. 16E. Once detection of the two thumbs1604-L and1604-R ceases, a screen rotation command with an angle of rotation opposite to the acute angle is executed, thereby restoring thedigital image1502 to a portrait orientation, as shown inFIG. 16F.

WhileFIGS. 6A-6D, 8A-8D, 10A-10C, 12A-12C, 13A-13C, 15A-15E, and 16A-16F illustrate scrolling, translation, scaling, and rotation operations in the context of aportable multifunction device100, similar operations may be performed on any device with a touch-screen display, in accordance with some embodiments.
